Special Issue Information

Dear Colleagues,

Carbon nanotubes (CNTs) are unique carbon nanomaterials with a hollow tubular structure formed from rolled graphene sheets, which can be classified into single-walled CNTs (SWCNTs) and multi-walled CNTs (MWCNTs). Since their discovery, CNTs have attracted significant attention owing to their remarkable physical, chemical, and electronic properties. These unique characteristics, along with those of CNT-based composites, have enabled their integration into a vast range of technological fields, including electronics, biomedicine, energy storage and conversion, chemical processing, environmental remediation, and catalysis.

This Special Issue aims to highlight the latest advances in CNT research, with a particular focus on synthesis methods, characterization approaches, and technological applications of SWCNTs, MWCNTs, and hybrid CNT systems. For this Special Issue, original research articles and reviews are welcome for submission.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Nitrogen oxides represent a major source of concern related to atmospheric pollution, causing substantial impacts on human health. One innovative approach to reducing these emissions, and a promising alternative to conventional methods using NH3, is selective catalytic reduction with carbon (SCR-C). The aim of this study is the development of carbon-based catalysts that are active in the reduction of NO. For that, carbon nanotubes were subjected to treatments to modify their surface chemistry, including introducing oxygen and nitrogen groups, as well as potassium (K) and copper (Cu) incorporated as metal phases. In their original form, carbon nanotubes do not exhibit catalytic activity in reducing NO. However, catalytic performance is significantly improved by the addition of surface groups and Cu. Adding K to the support notably contributes to increasing the catalytic performance. N-doped carbon nanotubes impregnated with copper and potassium (CNT_M_BM@5Cu5K) achieved complete NO reduction at 360 °C. In this catalytic system, the formation of CO2 and N2 was observed and CO was not identified. Furthermore, although N2O was detected during the reaction, its amount was very low compared to the N2 and CO2 products. The stability of this catalyst was investigated over 87 h continuous test, revealing deactivation after 41 h of reaction. Full article
